An invisible anti-theft net

Abstract

The invention belongs to the technical field of security and protection facilities and particularly relates to an invisible anti-theft net comprising an upper beam, a lower beam and steel wires. The upper beam comprises an upper frame body, an upper mounting plate is connected to the upper frame body, and upper mounting holes are formed in the upper mounting plate. Upper wire penetrating holes areformed in the bottom of the upper frame body, wire outlet holes are formed in the rear side wall of the upper frame body, and a fixing mechanism is connected to the rear side wall of the upper framebody. A wire winding mechanism is mounted in the upper frame body, the lower beam comprises a lower frame body, and a lower mounting plate is connected to the lower frame body. Lower mounting holes are formed in the lower mounting plate, and lower wire penetrating holes are formed in the top of the lower frame body. Fixing heads are connected to the lower ends of the steel wires and mounted in thelower frame body, and the steel wires sequentially penetrate through the lower frame body and the upper frame body, are wound around the wire winding mechanism and then penetrate through the rear side wall of the upper frame body to be connected with the fixing mechanism. According to the invisible anti-theft net, the mounting process is simple and rapid, and after tension of one certain steel wire is reduced or the certain steel wire is broken, the other steel wires can still take the protection effect; and the later-period maintenance time can be shortened, and the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of security facilities, and in particular relates to an invisible anti-theft net. Background technique [0002] The invisible anti-theft net is a kind of anti-theft net used for protection and anti-falling objects. It is not invisible, but is wound tightly by a 2MM thick steel wire between the fixed profiles at the outer end of the window. The distance between the steel wires is fixed at 5CM. It can withstand a pulling force of more than 85-120KG, which can ensure that thieves cannot tear it off. Because there is a 5CM distance between the steel wires, people cannot drill in from the gap, so it can effectively play the role of anti-theft protection. [0003] The high-performance invisible anti-theft net is specially designed with a steel wire cutting alarm function. When the thief cuts the steel wire, the intelligent alarm connected to the steel wire will send out an alarm signal. The alarm is carried out in...

AI Technical Summary

Problems solved by technology

[0005] Although the above technical solutions can play the role of anti-theft, but in the installation, it is necessary to bypass all the winding posts, the workload is heavy, the installation is troublesome, and once the tension of a certain steel wire rope becomes soft or broken, will cause the entire anti-theft net to lose its original anti-fall and anti-theft function
